I'll toss in a bit...
I spend a fair amount of time in bombers, since I'm more likely to accomplish something in them!
The hardest attack to defend, IMO, is the high slash "across the shoulders". By this, I mean attacking from altitude, almost directly overhead, diving in over the wingroots/cockpit/top turret. Very hard to keep a consistent defensive gun lead on a slashing angled attack, across multiple gun locations. Also, from this angle, only 2 of each bomber's 10 guns can come to bear. From dead-6, you'll get 14 guns!
I will do you some serious harm if you come in from any angle flat. Headons co-alt are no problem. Down low I can see you climbing up to me, so I'll pin you underneath before you get to me. Go high. Very few ever do. Last night, however, someone knew his stuff (can't remember who) and tore me up with these slashing attacks.
Usually, I can watch a fighter come in...settle nicely behind the "blind" bomber formation...blissfully unaware that I've been watching for 10 minutes (nuttin' else to do!). I like to hold fire a bit to lure them in closer. You'll think you've found a n00b! Once you're within 1k, you'd better have your chitterlings together 'cause you're gonna get shredded unless you have blazing speed and strenuous angles to keep me hopping...or unless I get hit with wife-ack which seems to have a 100% lethality rate in my version of AH.
I'm not a fighter master, but I do like a good buff hunt. There are many competent aircraft for bomber hunting, but I found that the 109 with 20mm gondolas will climb to the meat in no time flat, with plenty of speed to maneuver and 3 big kannones for chewing off pieces of bomber. However, don't get caught in a dogfight cause she turns like a pig with gondies. Just be precise with your gunnery.
